Parameters
instance instance-id: Configures the device as the root bridge in a particular MSTI. The value of
instance-id ranges from 0 to 32, where 0 represents the CIST.
vlan vlan-list: Specifies a VLAN list in the format of vlan-list = { vlan-id [ to vlan-id ] }&<1- 1 0>, where the
vlan-id argument represents the VLAN ID, in the range of 1 to 4094, and &<1- 1 0> indicates that you can

Description
Use stp root primary to configure the device as the root bridge.
Use undo stp root to restore the default.
By default, a device is not a root bridge.
To set an MSTP device as the root bridge in a specific MSTI, use this command with the MSTI specified.
To set a PVST device as the root bridge in a specific VLAN or multiple VLANs, use this command with a
VLAN list specified. To set an MSTP device in the CIST or an STP/RSTP device as the root bridge, use this
command without specifying any MSTI and VLAN.
Once you specify the device as the root bridge, you cannot change the priority of the device.
Related commands: stp priority and stp root secondary.
